What is Stepoc?

Stepoc is a precast concrete block retaining wall system that can be laid dry. Stepoc blocks are hollow which allows for reinforcement bars to be inserted and for concrete to be pumped down through the inter-connected cavities in the blocks. The blocks unique design creates a cascade or waterfall effect which ensures a smooth filling of the pumped concrete, forcing out air and eliminating segregation, to create walls which have immense compressive and lateral strength.

The benefits of Stepoc

1. Build (almost) anywhere with Stepoc - Difficult plots you'd discounted are now viable development sites.
2. Build fast with Stepoc - Stepoc is stacked dry, for fast construction of a single skin wall.
3. No specialist skills required with Stepoc - Build retaining walls with general site labourers. No bricklaying skills required.
4. No hanging around with Stepoc - No mortar, no drying time, no waiting. Stepoc walls fly up.
5. Stepoc is solid as a rock - Fill the cavity with a single pour of concrete to create a reinforced wall.
6. Stepoc is cheaper than alternatives - Pound for pound, built Stepoc retaining walls are cheaper than equivalents

Examples of construction using Stepoc:

  • Retaining walls
  • Basement walls
  • Flood alleviation schemes
  • Swimming pools
  • Blast panels
  • Lift shafts
  • Platform edges

Stepoc FAQs

No, unfortunately Ibstock does not offer this service. We can however carry out a take-off to determine the number of blocks.
We would suggest a maximum distance of 20m between movement joints but the final decision lies with the engineer designing the structure.
The following volumes of concrete are for guidance purposes – 200mm Stepoc 0.12m³/m², 256mm Stepoc 0.15m³/m², 325mm Stepoc 0.19m³/m²
We would recommend a maximum of 8 courses for 200mm Stepoc and 10 courses for 256mm and 325mm Stepoc, however final pour height will be determined by the construction sequence on site.
We would recommend the use of a concrete pump; however in restricted situations the use of other methods can be employed. It is important to use a fluid concrete mix with a minimum 150mm slump to allow the concrete to flow through the blocks.
There are 11.11 blocks per m² of wall for 200mm and 256mm Stepoc and 13.6798 blocks per m² for 325mm Stepoc.
Please refer to our brochure (page 54) for further information.

We would recommend that any free ends and corners are temporarily propped prior to filling.
Yes, standard brick ties can be built into the Stepoc walls as they are constructed as the block height of 225mm coordinates with traditional brick and block coursing.
Yes, we would recommend this is carried out prior to filling the wall with a hole being cut through the blocks and PVC pipe or other preparatory system being employed.
Yes, We would recommend speaking to a fixing specialist who will be able to determine the correct type of fixing for your particular situation and loading.
We would always recommend speaking with a waterproofing specialist prior to undertaking any product application and also ensure that the method meets the guidelines set out by the NHBC or other warranty provider where applicable.
The face of Stepoc is quite close textured and can be left unfinished, however in the majority of situations an additional finishing layer would be normal practice.
We can normally dispatch blocks within 1 week of an order being placed.
Yes this is possible, please contact the Technical Department for further details - call: 0333 234 3434 or email: anderton.structural@ibstock.co.uk
Yes, it is possible to construct curved structures using Stepoc. Please contact the Technical Department for further details.
The wall once in-filled with concrete will provide a Thermal Conductivity (k value) of 1.60 W.m-1.K-1) (figure taken from CIBSE guide)
We would recommend that backfilling takes place approximately 7 days after the concrete has been poured but the final decision lies with the engineer designing the scheme.
Please refer to the Transport Options guide for further information.
